Bunostomiasis or Bunostomiosis is caused by Bunostomum trigonocephalum and B. phlebotomum parasite.
Bunostomum trigonocephalum
- Host: Sheep, goat and cattle (rarely).
- Location: ileum and jejunum.
- Life cycle: Similar to Ancylostoma, prepatent period: 30 – 56 days.
Epidemiology
- Similar to Ancylostoma.

- Mixed infection of Strongyle sp and Bunostomum sp are common.
Clinical manifestation
- Anaemia, oedema on intermandibular region – “Bottle jaw”.
- Diarrhoea is not infrequent, faeces is dark in colour due to altered blood pigments.
- Prostration and finally death.
Diagnosis
- Based on clinical signs.
- Faecal examination.
Treatment
- Fenbendazole @ 5.0 mg /kg b.wt.
- Albendazole @ 7. 5 mg /kg b.wt.
- Thiabendazole @ 75 mg /kg b.wt.
Control
- Avoid wet floor shelter – larvae highly susceptible to dryness.
Bunostomum phlebotomum
- Host: Young calves, sheep is rarely affected.
- Location: Duodenum.
Clinical manifestation
- Anaemia, diarrhoea and submandibular oedema.
- In stabled cattle causes itching and stamping of legs.
